SHAPING OFYICE CREAM Filed Nov. 1, 1937 Patented Sept. 10, 1940 UNITED STATES PATENT OFFICE -SHA PING F ICE CREAM Hermann Gothe, Potsdam; Germany Application November 1,1937, Serial No. 172,237

In Germany November 4, 1936 3 Claims.

My invention relates to means for forming ice cream into portions and more especially to the production of portions of ice cream of a novelkind, which are composed of difierent kinds of ice cream extruded in different streams, one or several-streams being surrounded by or envel-' oped in one or a plurality of other streams, pref erably in such manner that each portion has the contours of or represents an image, for instance an animal, a flower or the like. L

With an extruding device according to my invention I am able to dispense ice cream under a particularly pleasing form and my device enables me to quickly divide and dispense ice cream with I a minimum of expense.

' I prefer combining this device with a refrigerator of some suitable kind, in which the extruded streams are cooled down to the extent of attaining the best degree of hardness and bezo coming suitable to be cut into portions.

so surround the ends of one or a plurality of extensions of the inner containers so that the diifer-- ent streams of ice cream extruded from the outer containers will meetand surround the ice cream extruded from the inner container or containers.

35 In the drawing affixed to this specification 'and forming part thereof some embodiments of my invention are illustrated diagrammatically by way of example.

In the drawing:

40 Fig. Us a perspective diagrammatic view of the combination of two outer containers and one inner,container, all ending in a conmion' mouthpiece.

Fig. 2 is a similar view, drawn to adarger scale, ,of the mouth-piece.

Fig. 3 is a diagrammatic axial section of the combination of parts shown in Fig. 1, in which the inner mouth-piece is rendered exchangeable. Fig.4 is a-similar view, drawn to a larger scale, 50 of the mouth-piece proper.

Fig. 5 is a plan view of a refrigerator adapted. to cooperate withthe dividing device, and .Figs. 6 and A are diagrammatic sections, drawn to a larger scale, on the lines VIVI and VlIVH of 55 Fig. 5, respectively. J

,from these containers.

Fig. 8 is a view, similar as Fig. 3 of a combination with two inner containers.

Referring to the drawing and first to Figs. 1 to 4, I is the foundation plate of the dividing and portion forming device and 2, 3 and 4 are 5 three cylinders mounted in apertures formed in. this plate, while 5 is the mouth-piece being the combination of three funnels 6, I and 8, the funnels I and 8- located below the outer cylinders 3 and 4 surrounding the funnel 6 located below the 16 inner cylinder 2. As shown in the drawing, the bottom end of the inner funnels 6 is contracted and shaped in such manner that itsedge forms the outline of an animal (a bear) while the outer funnels l and 8 converge towards the inner fun- 15 nel 6, the top part of their edges being spaced from the bottom edge of the inner funnel 6, which thus projects into the path of the ice cream issuing from the cylinders 3 and 4-. 29, 30 and 3| are pistons reciprocating in the containers '2, m

3 and 4,- respectively, with their piston rods connected with each other for extruding ice cream 9 is the exhaust opening of the mouth-piece proper.

.In the modification shown in Fig. 8 the inner container is divided by the wall 6 'into two compartments 2 and 2 in which reciprocate pistons and 301 respectively.

The funnel 6 of the middle cylinder is preferably arranged to be readily exchanged, so that 30 1 various outlines of the middle part of a portion can be formed. The funnel may be connected with the bottom of the container 2 by means of screws and bolts as illustrated in Fig. 3.

In order that the different kinds of ice cream 5 can be assembled in a well defined manner, the bottom edge ll! of the mouth-piece is preferably located somewhat below the bottom edge I I .of the funnel 6 (Fig. 4) and the exhaust ends of the mouth-piece and the funnels are preferably con- 40 ical.

' In order to prevent the ice cream issuing from the innercylinder or cylinders from acquiring an unduly high degree of hardness when surrounded by the outer ice cream sections, I prefer lining .the bottom; parts of the funnels with .a heat'insulating, lining I 2, and I may also provide means for heating the exhaust ends of'the funnels and mouth-piece. r

The skeins formedwith the aid of the device here'above described are, preferably cooled in a. refrigerator such as shown in Figs. 5 to 7, w erein 2| is the body of the refrigerator, while 2 are parts of a tube system, in which circulates a coolin! liquid of some well known kind, while 23 are canals traversing the refrigerator body and serving for cooling the ice cream skeins, which are conveyed from the dividing device into these canals by means of conveying belts 24 or 25, re-

- spectively.

Fig. 6 is a cross section of a conveyor such as shown in the top row of canals in Fig. 5, the endless belt 24 passing around cylinders 26 and over guide cylinders 21, so that both reaches of the belt pass through the same canal 23, 28 being a plateseparating the two reaches.

In the modified form of the conveyors shown in- Fig. '7 the conveying belt 219 is passed around two pairs of cylinders 30, 3|, which are so arranged, that one reach of the belt extends through one canal, the other through the adjoining canal.

The ice cream portions are either stored in or passed slowl through the canals 23 and frozen hard, while during the-shaping process occurring in the extruding device the cream must be more plastic.

Preferably short wooden sticks are stuck in the portions to serve as handles.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.

I claim:

1. An ice cream extruding device comprising in combination, an inner container, a plurality of outer containers flanking said inner container, funnel-shaped mouth-pieces associated with said outer containers, a mouth-piece associated with said inner container and surrounded by the mouth-pieces of said outer containers, the edges of the outer mouth-piece projecting beyond the edge of the inner mouth-piece, and means for simultaneously extruding ice cream from each 01' said containers through said mouth-pieces.

2. The device of claim 1, inwhich the inner jecting beyond the edge of the inner mouth-piece,-

and means for simultaneously extruding ice cream from each of said containers'through said mouthpieces.
